CASEMENT-WINDOW MOUNTING.

Application filed May 10,

This invention relates to hinged windows which are usually mounted either to swing outwardly or to swing inwardly. Inwardly swinging windows have many advantages but are hard to make water-tight. Outwardly swinging windows are easily made watertight but it is difficult to fit them sat-1sfactorily with fly screens or casement windows.

My object therefore is to devise casement window mountings which will enable me to close the bottom ofthe window against the outside of the inner sill to prevent leakage and, when desired, to raise it to open inwardly. A further object is to so arrange the mountings that the window may be held open in different positions as desired or firmly locked in the closed posltlon and pressed against its stops.

I attain my objects by means of h1nges which permit of a vertical movement of the window on the axes of the hinge pins so that after the window has been swung to it may be lowered to bring its bottom in front of the inner sill. In connection with at least one of the hinges is provided cam mechanism whereby the window may be raised or lowered at will and when raised may be swung to and from the closed position.

The invention is hereinafter more fully described and is illustrated in the accompany ing drawings in which Fig. 1 is a vertical section of a casement window provided with my improved mountmgs Fig. 2 a sectional plan of part of the same;

Fig. 3 an elevation of a hinge in its lowered position;

Fig. 4 a similar view with the hinge in its raised position; I

Figs. 5 and 6 are views similar to Figs. 3 and 4C of a modified form of hinge; and

Fig. 7 is a side elevation of part of a window and frame, showing particularly the locking means.

In the drawings like numerals of reference indicate corresponding parts in the different figures.

Referring particularly to Fig. 1, 1 is the window frame which is formed with the 1926. Serial No. 108,186.

usual outside sill 2 and inside sill 3 at a higher level than the outside sill. 4 are the usual stops against which the window closes from the inside. The window frame is cut away at 5 to permit the window 6 to rise suificiently to clear the inside sill. A strip 7 is secured to the window sash to cover the gap when the window is closed and lowered. The window is provided with hinges which permit the window to be raised and lowered. to One or more of the hinges will be provided with means whereby the window may be raised and lowered and releasably held in the raised or lowered positions. For a small window it is sufiicient that two hinges be employed, the lower of which will be provided with the raising and lowering mechanism referred to.

In the drawing I show the upper hinge as comprising two hinge members 8 and 9, one secured to the window frame and the other to the window sash. The member 8 has two spaced hinge knuckles 10 formed thereon while the hinge member 9 has one hinge knuckle 11 adapted to slide on the hinge pin 12 between the knuckles 10.

The lower hinge construction is shown in Figs. 3 and 4;. The hinge member 13, which is secured to the window frame, has a knuckle 27 formed thereon provided with a cam slot 28 provided at top and bottom with the dwells 29 so that the pin 36 hereinafter referred to may rest therein to lockthe window up or down. The hinge member 14 connected to the window sash is provided with the knuckles 30, 31 spaced apart sufficiently to permit of the hinge member 14 rising and falling relative to the hinge member 13. A hinge pin 32 extends through the knuckles and has secured thereto below the lower knuckle 31 a collar 33. A collar 34 forms a head for the pin above the knuckle 30 so that the hinge pin is immovable lengthwise of the hinge member 14:. Between the hinge pin and the knuckle 27 is located a sleeve 35 which extends up into contact with the knuckle 30. This sleeve is secured to the hinge pin by means of the-pin 36 threaded into the hinge pin, which pin 36 moves in the cam slot 28. An operating handle 37 is sethe sleeve 20.

cured to the lower end of the hinge pin, which is extended downwardly to any convenient position.

It is evident by swinging the handle 3'? that the pin 36 will ride up and down in the cam slot in the knuckle 27 and raise or lower the window.

In the lower hinge construction shown in Figs. 5 and 6, the member 13 is lined to the window frame and is provided with the knuckles 15 and 16, and the member 14 is secured to the sash and is provided with knuckles 18 and 22. A hinge pin 17 extends through the knuckles and is held in position by a screw and washer 19. Between the knuckles 18 and 22 a sleeve 20 is positioned on the hinge pm. This sleeve is longitudinally movable on the hinge pin but is held from rotating by a projection 21 having a groove engaging the hinge member 13. The knuckle 22, when the window is lowered, is spaced from the knuckle 16 of the hinge member 18. A pin 23 extends through the hinge pin and into cam slots 24 formed in l hese slots are provided at opposite ends with the dwells 25 similar to the dwells 29 so that the sleeve may be locked by means of the pin 23 in either its up or down position. One end of the pin 23 is preferably extended to form a handle 28 by means of which the pin may be swung to raise or lower the window.

The construction shown in Figs. 3 and l, it will be noted, differs from the construction shown in Figs. 5 and 6 in that in the former case the hinge pin moves longitudinally with the sash member 14: whereas in the other case it does not move as it is car ried by the frame member 13.

The fact that the window is capable of being raised and lowered enables me to provide simple means for holding it open in any de sired position. These means comprise a rack 38 secured to the inner window sill with which a projection 39 on the bottom of the window sash is adapted to engage.

Assuming the window to be closed, the mode of operation is as follows. The operating handle, which will normally be substantially parallel to and extending in the same direction as the closed window, is swung back to the left. This raises the window sufficiently to clear the inner sill. The handle l0 may then be grasped and the window swung open as far as desired. If it is to be locked by means of the rack 38 and projection 39, the handle of the operating mechanism is swung back suilictiently to wards, its original position to lower the window and engage the projection with the rack. When the window is to be closed, the handle is operated to lift the window, which is then swung to its closed position with its bot tom edge in front of the inner sill. The operating handle is then swung to the right and the window forcibly lowered in front of the inner sill.

To cause the window to be pressed firmly against the stops 4, I provide the wedgeshaped keepers ell in the window frame behind which may engage theprojections 42 on the window sash; As the window is lowered, the projections 42 ride down the inclined faces of the keepers and the window is pressed firmly outwardly against its stops.

The invention is equally applicable to steel or to wooden windows or to French doors.

hat I claim is:

1. A casement window hinge comprising a hinge part for connection with a window frame; a hinge part for connection with a window sash; a hinge pin, the parts of the hinge being movable relative to one another axially of the hinge pin; raising and lowering means engaging the parts of the hinge comprising members adapted. to be moved axially of the hinge relative to one another, one of said members being'also manually rotatable on the axis of the hinge independent of'the relative swinging movements of the'parts of the hinge; a pin and cam slot connection between the two members whereby the rotary movement of the said member eifects the relative axial movement of the members and the raising of the window sash part of the hinge relative to the other, one of the members of the raising and lowering means, when the said hinge part is raised,

being adapted-to support the part so that it may swing freely in its raisedposition with- 'out rising or falling movement.

2. A casement window mounting comprising a sash hinge member having two spaced hinge kunckles formed thereon; a second or frame hinge member also having a hinge knuckle formed thereon of a length less than the space between the first mentioned knuckles, said knuckle having a cam slot formed therein; a rotatable hinge pin passing through the knuckles; a pin projecting from the hinge pin into theslot of the slotted knuckle; and collars on the hinge pin engaging under the other knuckles.

3. A casement win ow mounting comprising a sashhinge member having two spaced hinge knuckles formed thereon; a second or frame hinge member also having a hinge knuckle formed thereon of a length less than the space between the first mentioned knuckles, said knuckle having a cam slot formed therein; a rotatable hinge pin passing through the knuckles; a pin projecting rom the hinge pin into the slot of the slotted'knuckle; and a collar formed as a sleeve fitted over the hinge pin within the slotted knuckle and extending between the inner faces of the unslotted knuckles.

l. A casement window mounting comprising frame and sashhinge members each having, a hinge knuckle formed thereon, the knuckle of the frame hinge member having a cam slot formed therein; a rotatable hinge pin on Which the knuckles are relatively movable axially thereof; a pin projecting from the hinge pin into the slot of the slotted knuckle; and a collar on the hinge pin engaging under the other hinge knuckle, the

cam slot being provided With a dwell at each end whereby the slotted knuckle may be 1 of April, 1926.
